Message: Call to undefined method CI_Email::get_emails() codeigniter 3 - codeigniter-3

Question

I try build function in controller Codeigniter 3 to read emails from inbox and insert to database.
`public function read_emails() {
// Load the email and database libraries
$this->load->library('email');
// Connect to the POP3 server
$config = array(
'protocol' => 'pop3',
'pop3_host' => 'pop.gmail.com',
'pop3_user' => 'xxxxxxxxxxxx',
'pop3_pass' => 'xxxxxxxxxxxxxxxx',
'pop3_port' => 995,
'pop3_encryption' => 'ssl'
);
$this->email->initialize($config);
// Retrieve emails from the inbox
$emails = $this->email->get_emails();
// Loop through the emails
foreach ($emails as $email) {
// Check if the email was received within the last 24 hours
$received_time = strtotime($email['received_time']);
$current_time = time();
if ($current_time - $received_time <= 86400) {
// Check if the email already exists in the database
$this->db->where('email', $email['email']);
$query = $this->db->get('contacts');
if ($query->num_rows() == 0) {
// Insert the email into the database
$data = array(
'email' => $email['email'],
'subject' => $email['subject'],
'message' => $email['message']
);
$this->db->insert('contacts', $data);
}
}
}
}`
When I run this controller I get output:
Message: Call to undefined method CI_Email::get_emails()
Can anyone please help me debug this issue? Very important.
line 43:
// Retrieve emails from the inbox
$emails = $this->email->get_emails();

I don't know if codeigniter3's email class has such a get_emails() function, or if you can retrieve emails from the inbox.
Please check the official documentation: https://codeigniter.com/userguide3/libraries/email.html
If it is a custom class/plugin/addon, you should either publish its code or submit a link to the repo
